HOW SCR WORKS
SCR IN NORTH AMERICA
Selective Catalytic Reduction (SCR) is one of the most cost-effective and fuel-efficient vehicle emissions control technologies available to reduce diesel engine emissions.
SCR technology is designed to permit nitrogen oxide (NOx) reduction reactions to take place in an oxidizing atmosphere. It is called "selective" because it reduces levels of NOx using ammonia as a reductant within a catalyst system. The reducing agent reacts with NOx to convert the pollutants into nitrogen, water and tiny amounts of carbon dioxide (CO2) - natural elements common to the air we breathe everyday. The reductant source is usually automotive-grade urea, otherwise known as Diesel Exhaust Fluid, which can be rapidly hydrolyzed to produce the oxidizing ammonia in the exhaust stream. SCR technology alone can achieve NOx reductions in excess of 90%.
As the overwhelming choice of heavy-duty truck and engine manufacturers in North America to meet 2010 emissions standards, SCR diesel emissions control technology is being adopted into multiple upcoming product lines at this very moment.
Hino has adopted SCR and developed state-of-the-art technologies to implement emission controls that meet or exceed the 2010 EPA guidelines.
